In accordance with the invention winding drums are located on the frame of the truck tackle and may whereby the utility greatly enhanced,

.parts in-elevation,

and are provided with means whereby the drums may be rotated for actuating lifting be braked or otherwise held lifted load is maintaine against dropping or lowered under "control, or other operations are performed-by means of the power furnished by the power unit of the truck, at the will of the operator.

The invention is adaptable to existing automobile trucks with a'minimum of change, of the truck. is very while. the cost of the attachment and the amount of work needed to apply the attachment is minimized.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming art of this specification, with the understan ing, however, that the invention is not confined stationary when a to any strict conformity with the showing truck.

and brake means therefor, but with the driv- 111%11163118 omitted.

ig. 5 is a cross section of the truck frame and one of the winding drums, portions of the structure being omitted.

Referring the drawings there is shown a main chassls frame 1 which may-be constructed in accordance with the usual pracing of the engine or power unit 5 without any attempt power unit of commercial trucks.

to show details thereof, for the The engine 5 transmits power through the customary trans-' mission indicated by a transmission casing driving shaft represented by ing 7 leading from toward the rear of the machine. The driving shaft .7 is continued for an appropriate distance andis provided with a clutch 8, on

schematically repreany appropriate type,

view of such clutch sented by an exterlor without any attempt to show its more mi' nute construction.

need not differ from like parts The shaft 7 terminates in a universal j oint generally indicated, and this uniof another.drive shaft 10 inturn leading to the usual differential gearing on' the axle 2 and inclosed in a casing 11 of customary construction. The shaft 10 carries a worm inclosed in a-casing 12 and engaging a, worm wheel acting on the rear axle 2 through'the customary. differential, which latter is not shown as it need not differ from the'differentials ordinarily employed in connection with the worm drive of automobile trucks.

The shaft 7 includesa worm indicated by a worm casing 13 and this worm, through a worm gear inclosed in a worm gear casing 14, is used to drive incased and supported by the main frame or chassis througings 16 which may be made fast to the chassis. V The jack-shaft casing is indicated at 17 particularly in Fig. 2.

Forward of the jack-shaft there is provided a winding a jack-shaft 15 suitablyappropriate journal beardifi'erent diameters, but it isto be underthe blocks 23 may be adjusted forwardly or rearwardly as conditions may demand. The

shaft 21 is carried at each end by an eccentric 26 fast to the shaft connecting the two eccentrics. The drum 18 at the ends carries disks 28 each constituting an outer head for the respective winding surfaces 19 and 20 and also constituting a friction disk, the

' heads 28 being of like diameter.

Partly surrounding each head or disk 28 is a brake strap 29 fast at one end to a fixed part of the frame of the machine, as,-for instance, a cross beam 30, and at the other end to a cross beam 31 carried by posts 32 directed on a respective one of the guideways 24. The brake bands 29 where secured. to the cross beam 31- terminate in adjusting eye bolts 33, whereby the bands 29 may be taken up or let out as occaslon may require. The posts 32 are made firm and rigid in position by brace rods 34 and 35 which at the end remote from the posts may be secured to the frame of the chassis 1.

Fast to and'extending between the upper ends of the posts 32 is a rod 36 carrying a guide ulley 37 .free to rotate and slide on the rod.' ounted on theframe 1 to the rear of the jackshaft 15 are other guideways 38 similar to the guideways '24 and car ing adjustable journal blocks 39 for a rock sliaft 40 with eccentric blocks 41 at the end of the -rock shaft 40. There is a winding drum 42 carried by the shaft 40 but free to rotate thereon the same as the drum 18 is free to rotate on the shaft 27. The drum 42 is provided at the ends with friction heads or friction disks 43 partially surrounded by the brake straps'44, each with one end fast to an adj usting eye bolt 45 carried by the beam 31, and at the other end fast'to any convenient part of the chassis frame,-as, for instance, to a cross beam 46 secured to and extending between the longitudinal sidebeams of the chassis 1 and appropriately arched to provide a bearing for the rear end of the shaft 7 adjacent to the universal joint 9. The drum 42 may have a number of winding surfaces 45, 46, 47 of different diameters. 1

The jackshaft 15 carries friction disks or wheels 48 fast to said shaft and in the path of both the friction disks 28 and 43 with the friction disks 28 and 43 under the control ofthe friction bands 29 and 44. j The shaft 27 has secured to it a hand lever 48, and the shaft 40 has secured to it a lever 49, the two levers 48 and 49 being designed for manipiulation by an operator to move the respective friction disks into operative relation to the friction disks'46 or into operatlve relation to the brake bands 29 and 44 respectively. I

At the rear of the chassis frame there may be located a tool carrier 50.

Carried by the'side members of the frame near the rear end thereof are the legs of a crane 51 the crane legs being supported by hinged bolts 52 readily adjustable lengthwise of the chassis by means of holes or perforations 53 in the flanges of the side members of the chasis 1. In the particular showing of the drawings the crane is of the A type and may be of any height desired when lifted toward the upright position.

At the upper endthe crane carries aguide' sheave 54 for a rope or cabl 55 extending over the shaft and having at its lower end a hook 56 or other holding means, and at the end remote from the hook made fast to an adjacent portion of the drum 42. The upper end of the crane also has fast thereto another pulley 56 through which there extends a rope or cable 57 fast at one end to the pulley 31 and at the other end carried over the roller 37, from whence it is carried to an adjacent portion of the drum 18 to which it is secured.

The lever 48. as indicated in the drawings is provided with a thumb latch 58 engaging a'rack segment 59 on the adjacent journal bearing 23. The lever 48 is so situated as to be within convenient reach of the operator of the tractor or truck and the lever 49 is assumed to be provided with connecting means whereby the operator of the vehicle may conveniently reach it from the usual operators seat. Such seat and the connecting means are not shown in the drawings as they are common features of trucks or tractors where separated parts are operated from a common point. In like manner the clutch 8 is assumed to be operable from the drivers seat, the usual groove for the operating fork being indicated in Figs. 2 and 3 at 60.

It sometimes occurs that it is convenient to operate other mechanisms by the power unit of the truck when the driving side of the truck is disconnected and for this purpose the jackshaft 15 has a driving pulley 61 at one end and a pitman crank 62 or other suitable means at the other end. These The truck equipped as described is particularly valuable in pulling pipes or tools from oil wells or ordinary water wells and for various other uses to which it may be put where facility of transportation from place to place and of putting out the traction side of the vehicle in utilizing the power side is desirable.- When the machine .on the jack shaft, brake bands individual ward. of and I the loads to. ravitate the bands t is being transported from place to place, the friction bands 29 and 44 may be tightened to an extent to hold the friction disks 20 and 43 against motion, and these same bands may be used to hold any loads which may have been liftedito an elevated position, or maybe loosened to an extent to permit to any desired degree, en serving as brakes. The structure is such that when the power unit of the truck is connected to the jack. shaft 15, somev one or more of the drums 45, 46 and 47 may be utilized for adjusting the crane 51, or, by elevate or lower mz% desire.
